gamesindustry.biz is saying that Playstation Home will be launching in October. They found a pdf document on Sony’s developer site. The document lists these dates for the roll out:

Closed Beta (appx. 15,000 users): April – August
Open Beta (appx. 50,000 users): August – October
Service Live (50,000+): October

This is pretty cool because people will be able to sign up for the beta as we already know but know we have a time frame and know a bit more about how its going to be rolled out.
